Still, the guy’s a total maroon, and probably cannot be trusted with a firearm. If I was carrying an illegal firearm in NYC, I would be *damn* careful not to draw attention to myself unnecessarily. Turnstile jumping is one way to draw official attention, fast.
One innovation that NYPD adopted during the Giuliani/Bratton era was to process people stopped for "minor" offenses. They often discovered the guy would have warrants out on him for major stuff. The criminal personality violates the law routinely and chronically.
